.Patented ,Feu 24, 1931 UNITED STATES PATENT :OFFICE CHARLES A..yER'JOILA, OF SAN FRANCISCO, CALIFORNIA DISPENSING DEVICE Application4le'd'lllecember 17, 1929. Serial No. 414,728,

My invention relates'to improvements in dispensing devices for tubecontained products wherein rollers are' mounted in opposing relationupon .the front and back of a body and held in firm frictional contactwith said body and a tube mounted upon said vbody for pressing theproduct outwardly from thetube.

The primary object of my invention is to provide an improved device fordispensing the contents from collapsible metal tubes.

Another object is to provide an improved dispensing device which willfacilitate the expelling of plastic products from collapsiblecontainers.

A further object is to provide an improved device wherein pressure isapplied from the closed end of a collapsible tube to dispense a producttherefrom, the product being fully and etiicientl expelled from thetube.

Another o ject is to provide an improved dispensing device which islight and compact and upon which a collapsible tube of a product to bedispensed may be readily attached and detached as desired.

A further object is to provide an improved device of the characterdescribed which can be economicall manufactured and which is durable ande cient. v I accomplish these and other objects by means of the improveddevice disclosed in the drawings forming a part of the presentapplication wherein llke characters of reference are used to designatesimilar parts throughout the specification and drawings, and in which-Fig. 1 is a front elevation of my improved dispensing device with acollapsible tube of a product to be dispensed mounted thereon; Fig. 2 isa side'elevation'of the device as 4shown in Fig. 1; s v

Fig. 3 is a side elevation of the device j after a portion of thecontents of thetube have been dispensed;

V Fig.` 4 is a sectional view of the device 'taken uponthe line 4-4 ofFig. 3 in the direction indicated and showing the manner in'which thetube is collapsed; and

Fig. 5 is a broken detail view, drawn upon 5 an enlarged scale, as'showing the manner in -hold said closed end of the tube.

vially through the rollers. The springs 14 which the closed end of thetube is engaged.

Referring to the drawings, the numeral -1 1s used to designate ingeneral a body, preferably formed from suitable sheet metal. The body 1is provided with flanges 2 along 55 the longitudinal edges thereof, andrearwardly ofset mounting bracket portions 3 are formed at the ends toengage and hold the body in spaced relation to a wall or other suitablesupporting surfaces. An opening 4 is preferably formed in the upperbracket portion 3 whereby the body may be suspended upon a screw orother suitable supporting member, not shown.

A pair of tube engaging lugs 6 are struck outwardly fromthe bodyadjacent the upper end thereof. The lugs are preferably ar. ranged toextend over the clamp member7 commonly applied u on the closed end of acollapsible tube `8 o the ordinary and well 70 l known form, said lugspreferably having sufficient resiliency to grip and eifectually Ashouldered bead 9 is preferably formed along the free ends of the lugs 6to seat the edges of the 75 clam member 7 of a tube and prevent said memer 7 and the end of the tube from being forced downwardly out ofengagement with the lugs. An annular band 11 is preferably mounted uponthe body adjacent the lower end thereof to receive the tube and holdsaid tube in proximate parallel relation to the body.

A pair of rollers 12 and'13 are mounted in opposing relation upon thefront and back of the body 1. The back roller 13 is received between theflanges 2 and engages the back surface of the body 1. The front roller12 extends the full width of the body 1.- Spring members 14 are mountedat the' ends of the 90 rollers 12 and 13, said members 14 bein providedwith bearing portions-16 rotatab y engaging the ends of shafts 17extending axnormally exert a pressure holding the'rollers 95 infirm'frictional engagement with the front and back of the body 1. A knob18 is secured upon an outwardly extending end of the shaft 17 of one ofthe rollers whereby said roller im may be rotated and both rollers movedlongitudinally along the body 1. A pair of gears 19 may also be mountedif desired upon the shafts 17 in meshing relation to impart rotationfrom one of the rollers to the other.

Hooks 21 are preferably struck from the body 1 adjacent the lower endthereofto receive a tooth brush 22 or other object to be used with theproduct dispensed.

In operation, the rollers 12 and 13 Aare moved to the extreme top of thebody 1, and a tube 8 of a product to be dispensed is mounted upon thebody 1 by inserting the closed end of the tube under the lugs 6, theoutlet end of the tube being inserted through the band 11. When therollers are rotated in the directions indicated by the arrows in Figs. 2and 3 of the drawings, said rollers, being held in frictional engagementwith the front and back of the body 1 by means of the spring members 14,willA be rolled downwardly past the lugs 6 and the outer roller 1 2 willbe moved' to engage the closed end of the tube 8.

When it is desired to dispense a portion of the contentsl of the tube 8,the usual cap 24; screwed onto the dispensing tip 25 of thc tube isremoved, and the knob 18 turned in the direction indicated in Fig. 2,thereby rolling the outerroller downwardly onto 'the tube 8 and imposinga pressure sufficient to expel i a portion of the contents from thetube. As the roller 12 is moved downwardly, the roller 13 is moved acorresponding amount so that 4the rollers will bear upon opposite sides0f the body and cause the tube to be pressed flat against the front ofthe body 1, as shown in Fig. 3, thereby completely expelling thecontents of the tube downwardlytoward the dispensingoutlet. As thecontents of the tube are displaced entirely by pressure from the closedend of the tube, the unemptied' portion ofthe tube will be kept expandedto its full symmetrical size, thereby presenting a neat appearance andpreventing the unsightly distortion commonly encountered. After thedesired amount of the product has been dispensed, the cap 24 is screwedonto the tip 25 to retain the remainlng product within the tube.

My improved device is particularly useful for dispensing .dentifrices,and in this connection, the hooks 21 afford a convenientv means forhanging tooth-brushes 22 upon the body 1.

While I have illustrated and described only one specific structure ofmyimproved dispensing device, the details of construction are of coursesubect to modification in. nu-

merous ways. without departing from the spirit of my invention, and Itherefore desire. to avail' myself Aof all modifications in structureand arrangement which may fall Within the scope of the appended claims.
